VC Megafunds Push for Bigger War Chests
Multiple prominent venture firms are raising substantially larger funds as capital concentrates at the top of the VC market. Reports say Founders Fund is planning a ~$6 billion growth vehicle, Spark Capital is raising about $3 billion (boosted by an early Anthropic bet), and General Catalyst is seeking roughly $10 billion for new funds. PitchBook data shows funds over $500 million accounted for more than half of venture capital deployed in the last four years despite representing a small share of funds by count. The newsletter also notes related AI and infrastructure signals: a data-center expansion in Abilene tied to Oracle and OpenAI faced financing friction after OpenAI stepped back, and a range of startup funding and geopolitical risks were summarized in the week’s roundup.
Large fundraising by multiple top VC firms signals continued capital concentration, which changes startup financing dynamics and access to the largest AI and tech deals; it affects venture allocation, LP strategies and the competitive landscape for later-stage financing.

Venture Giants Return: Billions Flow into Mega Funds
TechCrunch reports a resurgence of mega venture funds in 2026 as several prominent VC firms pursue multi-billion-dollar raises. Thrive recently closed a $10 billion fund, and General Catalyst is reportedly in talks to raise $10 billion after an $8 billion 2024 fund. Spark Capital is attempting to raise about $3 billion, Founders Fund is nearing a $6 billion close, and Andreessen Horowitz announced $15 billion in new funding in January. PitchBook and the National Venture Capital Association noted record dry powder at the end of 2025, and the influx of large funds is expected to sustain sizable early-stage financing—especially for AI startups—throughout 2026.
VC Concentration, Inception Investing, Big AI Rounds
This enterprise IT/VC newsletter analyzes the growing concentration of venture capital, investment strategies for winning market share, and the accelerating shift toward agentic and domain-specific AI. It highlights that a16z raised $15B (about 18% of venture last year) and that four firms accounted for 40% of venture funding, arguing investors must specialize by stage or go big. The author describes boldstart’s focus on “Inception” rounds and Intuitive TAM, notes Fund VII at $250M and $15M inception checks for select founders, and celebrates Tres Finance’s $130M exit to Fireblocks led by boldstart. The piece also summarizes recent enterprise AI and security funding and M&A activity (e.g., Anthropic, Cyera, Observe, Koi, CrowdStrike/SGNL) and flags agentic AI, Physical AI in robotics, and execution/observability gaps as key infrastructure opportunities for 2026.
Venture Capital Concentrates Heavily in AI
Analysis of U.S. venture capital activity in early 2026 finds unprecedented concentration in AI: 86% of U.S. VC spending in H1 2026 went to AI companies, with just two firms (OpenAI and Anthropic) receiving 53% of venture dollars. Mega rounds over $100 million accounted for nearly 88% of deployed capital in H1 2026 while smaller rounds drew only 12.5%. Funding for non-AI sectors (biotech, fintech, healthtech, cybersecurity) has fallen roughly in half since 2021. Capital is also concentrating at the fund level: the 10 largest venture funds captured 43% of capital committed in 2025, and the three largest brand-name firms captured 48% of commitments in H1 2026. The piece warns this top-heavy allocation raises systemic risk for innovation and public-market pipeline diversity.
